具有 OutlineBox 样式的 TextInputLayout 的可见性无法正确设置为 GONE

Question

我在 ConstraintLayout 中有三个具有 OutlineBox 样式的 TextInputLayout，如下所示。在 activity onCreate 中，我不需要显示最后一个，因此我使用这段代码（我使用的是 Kotlin）将其可见性设置为 GONE：etCompanyName.visibility = View.GONE.但正如您在图片中看到的那样，布局中仍保留一条窄线。我该怎么做才能正确消失 TextInputLayout？

<android.support.design.widget.TextInputLayout
        android:id="@+id/tilFirstName"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlineBox"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="16dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/etFirstName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/hint_first_name" />
    </android.support.design.widget.TextInputLayout>

    <android.support.design.widget.TextInputLayout
        android:id="@+id/tilLastName"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlineBox"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="16dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/tilFirstName">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/etLastName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/hint_last_name" />
    </android.support.design.widget.TextInputLayout>

    <android.support.design.widget.TextInputLayout
        android:id="@+id/tilCompanyName"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlineBox"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="16dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/tilLastName">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/etCompanyName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/hint_company_name" />
    </android.support.design.widget.TextInputLayout>

Answer 1

尝试设置可见性：属性文本输入布局元素而不是 editText。

tilCompanyName.visibility = View.GONE

具有 OutlineBox 样式的 TextInputLayout 的可见性无法正确设置为 GONE

The visibility of TextInputLayout with OutlineBox style can't be set to GONE properly
